  • About

    Professor Sih is investigating electron spins and photons in semiconductor nanostructures for potential applications in spin-based devices that combine logic and storage and for quantum and optical information processing in solid-state systems. Ultrafast, spatially-resolved magneto-optical spectroscopy explores electron spin coherence and electrically generating spin polarization in non-magnetic materials through spin-orbit coupling and the spin hall effect. The study of fabrication and optical characterization of prototype photonic devices, such as waveguides, ring resonators and photonic crystals, focuses on developing novel methods for controlling light.
